Specification of Letters Patent.

Patented Nov. 18, 1913.

To all whom it may concern:

Be it known that I, LEWIS S'rnmarm, a citizen of the United States, residing at Millville, in the county of Cumberland and State of New Jersey, have invented a new and useful Glassdirlachine, of which the following is a specification.

This invention relates to glass machines such as are intended particularly for use in manufacturing bottles and thelike.

The principal object of the invention is to provide a glass machine which is capable of producing two or more bottles at the same time.

Further objects of the invention are.to improve, simplify and strengthen the con struction of such machines, as well as to increase their automatic facility and to decrease the expense attending their manufacture, maintenance and use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it. being understood that changes in the precise embodiment of invention herein disclosed can be made within the sco e of the claims without departin from t e spirit of the invention.

Fig. 120 is a detail side elevation or" one of the depressible blank molds, showing the sprin s for raising it after it has been depressed Like reference numerals indicate corresponding parts in the ditierent figures of the drawing.

Briefly outlined, the apparatus of the present invention includes, among other things, a movable or semi-rotatable glass pot over which is disposeda stone slab having two circular openings threin with clay rings dependin r therefrom into the body of molten glass, tie function of the rings being to prevent any surface scum from being sucked into the blanks; a. movable element or rotary table having thereon a plurality of sets or pairs of blank molds and a plurality of sets or pairs of finishing molds, said blank and finishing molds being alternately arranged so that each finishing mold is located between two blank molds, and each blank mold between two finishing molds, the object being to permit two batches of glass to be simultaneously sucked intotwo of the blank molds and then by holoii said batches of glass stationary and rotat the table one step, to bring two finishing molds into position to receive said batches of glass while they arebeing blown into hottles; a set of hives or cutters-arranged on the under side of the table below each blank mold or batch for device, said sets of hives being connected inpairs so that two n sets of wives can be simultaneously operated to cut off two batches of metal; a vertically movable frame mounted above one edge of the table and directly over the stone slab and glass pot, so that web part of the i w periphery of the table can be successively brought into position beneath said vertically n ovable frame; a pair of neck rings carried by said vertically movable frame and provided with suitable means for opening and closing the same, said neck rings beingadapted to be moved downward into engagement with the pair of blank molds temporarily arranged there-beneath so as to force said blank molds downward into the molten glass and suck up two batches thereof; means for raising said frame and said "neck rings with the batches of glass suspended therefrom, out of engagement with said blank molds and for subsequently moving them downward into engagement with the pair of finishing molds which have been moved into position under-the frame at the same time that the blank moldswere moved out of position; means for moving blowheads, mounted on said frame, into position above said mold rings, and blowing the batches of glass into bottles; means for rotating the table another step, and means for opening the finishing molds to permit the removal of the formed bottles.

Referring to Fig. 1 of the drawings the humeral 1 indicates the glass tank; 2 the bridge wall; 3 the opening below said wall;

4 the passage for the molten glass; 5 the lating the flow of the glass; 7 the spout from which the glass discharges; 8 a, semi-rotatable glass pot supported on rollers 9 and operated by a shaft 10 having thereon a inion or gear wheel 11 which is engaged B a rack bar 12; and 13 a cylinder for reciprocating the rack bar 12 so as to impart a j semi-rotation to the pot 8.

The semi'rotatable pot 8 is covered by a casing 121 which serves to retain the heat of the glass and to prevent foreign substances from falling thereinto; [Above that portion of the put 8 from which the glass is to be withdrawn, is mounted a stone shelf or cover plate 15, the shape and details of which are est shown, in Figs. 13 and 1d of the drawing. The stone cover plate 15 is' formed with a pair of circular openings 16 into which are fitted rings it formed of clay or other suitable material, the 17 be of such valve controlled by the handle 6, for reguamass length as to project at their lower ends, be low the surface of the molten glass in the pot 8, as shown clearly in Fig. 1 of the drawings. It is to be understood that two of the openings 16 and rings 17 are shown in the cover plate 15 for the reason that the embodiment of invention illustrated is intended to form two bottles at the same time. If it be desired to arrange the machine in such same time, then three openings will be formed in the cover plate 15. It is to be understood, therefore, that the machine can be arranged in such manner as to manufac-' ture a larger number of bottles than two, at the same time, without departing from the spirit of the invention.

ment of the pot 8 accomplishes the same result as the rotatable pot without causing such a marked collection of seed, cord or irritation at the periphery of the molten glass as in the rotary pot. The rings 17 serve to prevent the extreme surface glass from being drawn into the blank molds for use in the making of bottles, and conse quently a superior grade of article is produced.

The rotary fable 18, shown in Figs. 3 and of blank and finishing molds, is mounted upon a'suitable ball bearing support 19 shown in Fig. 1 and is rotated in a step by step manner-by means of a gear wheel 20 fixed .on the lower surface of the table 18 as shown in-Fig. 4, and a gear wheel 21 having interrupted setsof'gear teeth as shown in Fig. 5, the gear wheel 21 being journaled on supports 22 shown in Fig. 1 and being operated by means such asv the belt wheel 23. The rotation of the belt wheel step manner. The table 18, as best shown in Fig. 3, has mounted on the upper surward through suitable openings therein, pairs of blank molds a-a, bb, 0-0, (l-Z. Each of the blank molds shown in Fig. 3 is constructed preferably as illustrated in detail in Figs. 7, 8 and9 of the drawings. That is to say, each blank mold is formed in two halves 25 and 26 suitably joined together and formed with converging suction passages 27 and 28,.half in one part of the blank and half in the other part, a radially extending slot 29 being formed at each side of the central opening 30 in the blank mold so that the efiect of the suction will be felt upward from the lower ends of the'sucthe blank mold. It is to be understood that after a suitable neck ring connected with a suction pipe has auatically fed manner as to produce three bottles at the.

The advantages derived from the use of the-semi-rotatable pot 8 and the rings 17 is that the backward and forward movetion passages 27 and 28 to the upper end of 4- of the drawings, which carries the pairs 23 causes the table 18 to rotate in a step by face thereof, and adapted to be forced down;

downward onto the upper end of each blank mold, said mold is forced downward through the table 18 and clay rings 17 of the cover plate 15 into contact with the glass in the tank 8, a batch of glass being then sucked upward into the blank mold by the suction action of the neck ring through the passages 27 and 28 and slots 29, the batch 'of glass filling the inner portion 30 of the blank mold.

For the purpose of raising the blank molds :ifter they have been pressed downward into contact with the molten glass, each of said molds is provided with a pair of oppositely extending ears or lugs with which are rigidly connected upwardly extending rods36 which pass through brackets 37 secured to the table 18 as shown in Figs. 2 and 20 and are provided at their upper ends with heads or enlargements 38, coil springs 39 being arranged around the rods 36 between the enlargements 38 and the brackets 37, the function of the springs 35) being to raise the blank molds titled with molten glass after the pressure by which they have been depressed is removed in the manner hereinafter described.

The means for depressing the two blank molds which are to receive batches of metal, sucking the metal into said molds, raising the neck rings with the metal batches suspended therefrom, out of engagement with the blank molds. lowering said batches into the finishing molds which have been moved thereunder, and blowing the bottles, will now be described. The reference numerals 40-40 in Fig. 2, indicate a pair of cylinders which are stationarily mounted above the table 18 in any suitable manner. The cylinders 40 are connected with each other in any suitable manner such as by means of the upper and lower frame pieces 41 and 42, and each of said cylinders is provided interiorly with a piston 43 which is guided in 'its movements within the cylinder by means of the piston rods 44. The two pistons 43 are lowered or depressed by means of compressed air which is fed to and exhausted from the upper end of each of the cylinders 40 by means of the air ipes 45, 46,, controlled by the valves 47'. I lach of the pistons'43 is raised, when the air pressure is removed from the upper facet-hereof, by means such as the coil spring 47 arranged in the lower end of the cylinder, exhaust vents 48 being formed in the lower end of each cylinder to permit the free operation of the piston 43 on the downward movement thereof. Secured to the lower end of each piston rod' 44 is a core or plunger head 49 and a core 50 which is intended to producethe initial blow-hole in the glass blank. The two plunger heads 49 are adapted to contact with the upper surface of a. vertically movable cross head 51, the core 50 being adapted to extend downward through a suitable opening in the cross piece 51 as shown in section at the left end of Fig. 2. The cross head 51 is fed downward by means of a centrally disposed hollow piston rod 53 which extends through a stationary cylinder 54 and has fixed thereon a piston 55. The cross piece 51 is likewise raised by the piston in cylinder 5-1, pressure heingadmitted above the piston as at 5-1 when it is desired to feed the cross head 51 downward, and pres sure being admitted below said piston as at 5 t when it is desired to feed the cross piece 51 upward. The hollow piston rod 53 isuscd as a conductor for the air which is used to blow the bottle and is also adapted for partial rotation for the purpose of opening the neck rings as will more fully hereinafter appear. Connected with the outer ends of the cross piece 51 are upwardly extending suction pipes (SO- 60 which are telcscopcd with suction pipes (ll--61, that are stationary with relation to the cylinders 40 and have connected at. their upper ends rubber suction pipes (32 connecting with a. common suction pipe 63. The movable suction pipe sections 60-430 at their lower ends communicate -withsuclion passages (54 formed in the ends of the cross piece 51 and controlled by vertically movable cut-oil valves (3?) having springs (it; for forcing them upward into closed position, and being adapted'to he opened agaipst the pressure of the spring on by means of transverse arms 67 connected with the plunger head ll), the 1m constriurtion being such that when the plunger head 49 is lowered into engagement with the. cross piece 51 the transverse arm ()7 opens the valve (55 and permits the operation of the suction for drawing molten glass upward into the blank, and when the plunger head 49 is raised out of engagement with the cross head51, the valve 65 automatically closes and shuts oil" the suction.

The two neck rings 70-70 shown in Fig. 18 of the drawings, are formed in two halves or sections 7l'71 mounted on crossed arm's. 72'73 pivotally mounted 'at 74 on the lower faces of the cross piece 51. The neck rings 70 are closed by means of coil springs 75 and 'are opened by means of oval shaped members 7G fixed on the rotary piston rod 53 of the cylinder 54. The two oval sha ed opening members 76 are arranged at tlie proper gngle with respect to each other as shown in The means for rotating the piston rod 53 to open the neck rings 7Q is best shown in Figs. 2 and '15 of the drawings and consists preferably of a cylinder 77 having therein a piston 78 connected with a piston rod 79 which is attached to an arm 80 fixed on the piston rod 53 adjacent the upper end thereof. When the operator desires to 0 en the neck rings, he turns any suitable va ve,

' position.

not shown, and thus admits pressure to the cylinder 71' so that the arm 80 is thrown into the position shown in Fig. 15, thus rotating the piston rod or shaft 53 in opening the neck ring. Upon releasing the pressure in the cylinder 77, the coil spring 7 5 shown in Fig. 18 returns the mold rings to closed The neck rings 70 are formed with suction passages 81 as shown in Fig. 18 which register at their upper ends with the suction passages 64; and at their lower ends with the suction passages 27 and 28, Figs. 7 and 8, in the blank .molds 26.

It will be obvious, that after two blank molds have been moved into position beneath the cross piece 51 in Fig. 2, the operator of the machine by manipulating the valve controlling the cylinder 54 can lower the cross piece 51 onto the blank mold withv the neck rings 70 fitting on the upper end thereof, and can force said blank molds downward against the tension of the coil springs 39 into engagement with the molten glass. By then manipulating the valves of the cylinders -10 he can lowerthe plunger head 49 into engagement with the upper surface of the cross piece 51, thus moving the core 50 into position to form the initial blow-hole in the glass, and at the same time causing the transverse arm 67 to automatically open the suction passages 64: so as to produce a suction through the neck ring and in the blank mold so as to suck up a batch of glass as shown in section at the left end of Fig. 2. By then manipulating 'the cylinder 54 to raise the cross piece 51,

said cross piece together with the neck rings and the glass batches hanging thereon will be drawn upward out of engagement with the blank molds 26 and will permitthe table 18 to rotateso as to move the two blank molds out of alinement with the glass batches, after which the cross piece can be lowered so as to feed the batches into position in the finishing mold so as to proceed with the blowing operation as will more fully hereinafter appear.

The blow-heads are indicated. by the reference numerals 90-90 in Figs. 2, 17 and 19 of the drawing, and are mounted for sliding movement in opposite directions upon the cross piece 51, each of said blowheads 90, as shown in Fig. 19, being provided with a downwardly extending dove-tailed portion 91 which is fitted tightly into a dove-tail groove formed in the cross piece'51 and slides therein under the combined action of a coil spring 92 and a bell crank lever 93 fulcrumed at 94 upon an upstanding arm or bracket 95 connected with the cross piece 51. The supply pipe 96 of the blow-head is connected by means of a flexible pipe 97 with the hollow piston rod 53 so as to get its supply of air therefrom. When the plunger head 49 is lowered in the position shown in Fig. 2, a pin 98 on the piston rod 44: en-

gages the bell crank lever 93 and depressesthe outer end thereof so as to cause the inner end thereof to retract the blow-head 90 out ofthe way of the plunger head 49 and when said plunger head 49 is raised above the cross piece 51, said head strikes the bell crank lever 93 and permits the coil spring 92 to throw the blow-head into position on the cross piece 51 above the neck ring 70. \V hen the blow-head 90 is retracted in the position shown in Figs. 2 and 17, the blow vent thereof is closed by the undercut groove in which the blow-headslides, 'but when said blow-head is moved into position above the neck ring, the blow pressure escapes through the ring and into the glass article to be blown.

v The molds into which the articles are to be blown, are equidistant from the center of ,the table and are arranged on the table 18 in pairs as shown in Fig. 3, as indicated by the reference letters e-e, f-'f, g-g, and hlz. Each mold consists of two halves, l00100 each mounted on an arm 101, fulcrumed at 102 and operated by means ofa piston cylinder 103 the interior arrangement of which is best shown in Fig. 12. Each piston cylinder 103 has therein a pair of oppositely movable pistons 104: each having a piston rod 105 and a coil spring 106. The coil springs 106 serve to move the pistons 101 toward the center of the cylinder, and air pressure admitted to the middle of the cylinder serves to operate said piston. The inner piston rod 105 of each cylinder is extended around the cylinder as indicated at; 107, and is connected with one of the mold arms, the other piston rod being connected cylinders 103, the. two molds are simultaneously opened and by turning the valve 110 which is a three-way valve, to another position, the air pressure is cut off and the air in the cylinder is exhausted through the valve when the coil springs 106 close the mold sections 100. It is to be noted from Fig. 3 that the,table 18 rotates in the direction of the arriiw and that the jaws of the mold when in open position are directed in they direction of movement of the table. This is to permit the mold sections 100 to clear the lower ends of the glass batches when the molds are moved into position be neath said batches As a modification of the invention, the

constantly c1 blank molds shown in Figs.

7 and 8 of the drawings, may be constructed so as to be opened and closed by the operator in the same manner as the mold, as shown in F igs. 10 and 11 of the drawing. That is to say, twin pistons may be arranged in a cylinder 103', these pistons being employed for opening the blank molds 100 by means of arms 101, and coiled springs may be employed for closin the molds in the same manner as disclosed in Fig. 12 with reference to the mechanism for actuating the molds 100. l

The means for cutting ot'i' the batches of lass after they have been sucked up into the blanks, is best shown in Fig. 4 of the drawings, and consists of a plurality of pairs or sets of knives 120 fulcrumed at 121 on the lower surface of the table, each pair of knives being arranged adjacent one of the openings through which the blank is forced downward into the glass metal. The knives 121 are connected with piston rods 122 and 123 of a cylinder 124 constructed the same as that shown in Fig. 12, the two cylinders 124 of each pair being connected by a common supply pipe 125 by means of which they ma be simultaneously controlled.

onstructed as described, the operation of the entire machine is as .follows: The table 18 is rotated so as to bring the blank molds a-a in-Fig. 3 directly beneath the cross .head 51 in ,Fi 2. By manipulating the cylinder 54 t0 ower the cross head 51 the neck rings 71 become seated on the upper ends of the blank molds 26 and force them downward through the openings in the table and through the clay rings 17 into engagement with the glass. While this is being done, the lungers 49 may be raised a slight distance aliove the cross head 51 so as not to waste any suction force until the glass metal is reached. By then lowering the head -19 to engagement with the cross piece 51., the

transverse arms 67 open the valves so as to permit'the suction 64 and through the mold rings and blank molds to suck the glass metal upward into the blank molds, the cores 50 serving to produce the initial blow-hole"in the glass batch. The cross piece 51,is then raised to its-highest position, thus causing the neck rings with the glass batches suspended therefrom, to move upward out of engagement with the blank molds 26. The table 18 then rotates one step so as to move the blank molds a--a in Fig. '3 out from under the cross piece 51 and to bring the moldse--e into position beneath the neck rings 71. At the same time that the open molds c--e are moving into position beneath the cross iece 51, said cross piece 51 is being moved ownward by the operator so as to feed the lass batches into the mold. The operator t ion manipulates the valve 11.0 in Fig. 3 to close the mold and at the same time manipulates the cylinthrough the passages ders 40'to raise the filling two of the blank molds,

plunger heads 49 so as to cause them to contact with the angle levers 93 and thus permit the blow-heads to slide over beneath the plunger heads l9 and blow downward through the neck ring so as to form the bottle. The operator then manipulates the cylinder 77 in Fig. 15 so as to open the neck rings 71 in Fig. 18 by slightly rotating the shaft 53. The'eross piece 51 is then raised far enough for the neck rings to clear the upper ends of the bottles and the table 18 is rotated one step so as to take. the finished bottles out of position beneath the cross piece and at the same time feed two more blank molds into position beneath the cross piece so as to receive the new batches. The two bottles which have been formed are permitted to remain in the molds for one or two steps of the table so as to enable them'to anneal, after which the molds areopened' and the bottles are removed. It will be understood that after the glass metal has been sucked up into the blanks in the manner described, the operator manipulates the valves of the twin cylinders 124 in Fig. 4 so as to cause the knives 120 to cut the metal below the table.

The machine of the present invention constitutes an important advance in the art as it is adapted to form a plurality of bottles at the same time. Moreover, a single set of neck rings and blow-heads cooperate successively with all of the blank and finishing molds during the operation of the machine.
